| General comment on data set | Masonry Cement is a MC 22,5 X cement which is produced and monitored in accordance with EN 413-1 (ES 8498-1). This cement is a hydraulically hardening binder for the production of concrete and mortar. It consists of a mixture of finely ground, non-metallic, inorganic components. After adding water to the cement, a suspension (cement paste) is formed, which solidifies and hardens both in air and under water due to the onset of a hydration reaction and remains permanently solid. The composition of the product corresponds to the specifications of EN 413-1 (ES 8498-1). |

| Technology description including background system | Masonry Cement is manufactured in the El Sokhna plant. Production of Portland cement clinker Limestone, marl, clay or their natural mixture, are required for the production of Portland cement clinker. These starting materials are mined in quarries, pre-crushed and transported to the nearby cement works. There they are homogenized into an intermediate product, with additional natural or secondary corrective substances being added to fine-tune the chemical composition. In the subsequent heating process, the Portland cement clinker is produced from the intermediate product. The firing process takes place in a rotary kiln, where the material is thermally converted at around 1450 °C and then rapidly cooled. The finished clinker is stored in silos. Extraction of limestone The limestone is extracted from natural deposits in open cast quarries. Cement production To produce the final cement product, the binder components are finely ground and combined. A sulfate carrier is added to control the setting behavior. |
